Abstract

The plunger has a rolling lobe, which is attached to a head end (1k) of an immersion bell (1) and an external side (1a) of the immersion bell forms a cylindrical shaped rolling surface for the rolling lobe. A closing plate (2) is provided, which is made of steel and contains a complementary carrier plate formed at the base end (1f), and a holding plate is provided, which is sealed in the carrier plate and held between immersion bell and carrier plate, where the carrier plate has a low specific weight than the holding plate.
